In connection with the polarizing interference microscope which incorporates Savart plates1), the theory of interferential-image-transferis formulated by introducing four-coherences between two linearly polarized light beams at pairs of points across a plane. By' Fourier transformation, the distributions of those coherences in image plane are mutually related to the ones in conjugate object plane under partially coherent illumination. This permits to describe analytically the effec-tiveness of source size compensation when the aberrations and finite aperture of the optical system are taken into consideration. Moreover, the expression with regard to coherence transmission of a Savart plategives a complete solution for spatial structure of interference phenomena and clari-fies the fact that a Savart of small lateral shear acts as a pupillary amplitude filter causing diffe-rential interference.
